1X 3 in aoou To all whom itgna-y conccrjnf Be" it known tlj atiL' Cnnnnvcn (LQRLS citizen .of the Unitedst ates, residingt nedy, 'in'the countyof Kittson and F Minnesota, have invented cor sin n useful Improvementsin ater-Gages, which the following is a specification.

This invention relates to water gages.

The object of my invention is to provide an indicator for steam andother boilers, constructed so as to'indicate the height or level of thewater within a boiler.

A further object of my invention is to provide an indicator adapted tomechanically register the height of a liquid within a receptacle, sothatthe same may be distinctly seen froma distance,

A still further object of myinvention is to provide a gage, constructedso that. the registering of the same may be seen from two sides. I

TVith-these and other objects in view, the present invention consist-sinthe co1nbination and arrangement of parts as will he hereinafter morefully described and particularly pointed out in the appended claim, itbeing understood that changes in the specific structure shown anddescribed may be made within the scope of the claim without departingfrom the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 shows vertical sectional view of a gage embodying my invention,Fig. 2 is an elevation, Fig. 3 is a view} on the line 33 of Fig. 1.

In the running of a steam engine, it is quite necessary in order to getthe bestresults, that the water level within the boiler be kept as nearas possible up to a predetermined point. The indicators usually employedfor disclosing the height of the water within a boiler, are made ofglass. The objection to this class of indicators is, that caving to theconstant changes of temperature to which these glasses aresuhjected,they frequently break, causing the. escape of steam and wa.

ter. Then, owing'to the inorganic matter held in suspension within thewater, and which is partly precipitated in the boiling oi the water, andwhich clings to the tube, the glass finally becomes so hcatetl, as tobecome opaque, and no longer'oi serviceas an indicator. In my presentinvention, I over- ITED STATES tear loosely carried upon within the,uet" shits" conic this objectionablefeature, 1n that'TI construct acylinder 6, provided with theth'readed boss 7. A The upper end of thecylinder is interiorly threaded, as shown at 8,, and held within thisthreaded end, is the screw top 8. Near the upper end the cylinder isfurther provided with the threaded boss 9. Near the upper end, and at apoint below and opposite the threaded boss 9, I provide the housing withthe laterally extending bearing box 11, which is closed by means of thevertically held plate 12, secured by means of suitable screws. Upon oneside, this box has the bearing lug 13, and registering therewith, is thebearing aperture l lextending through the packing gland 15, holding thepacking ring 16, the g and being threaded to receive the nut 17Revolubly held within these bearing apertures, is the rock'shaft 18,carrying the indicator 1.9 as clearly disclosed in Fig. 3. Hold to thistubular fioathousing, and adjacent to the bearing box upon the sidehaving the gland 15, is the bifacial, arcuate graduated member. 20provided with the perforated securing ends 21 by means of 1 preferablymade 'of 11011 01-1-0di1 metal, having the bottom which this calibratedmember is secured. The graduatlons winch are marked upon both sidesofthis bifacial scale 20, represent an indicia of quantity or volume, todisclose the amount of water within the boiler.

Loosely held within the housing, is the cylindrical float 23, the upperface of which is provided with the securing cars 24, and

the pin 25, held by these cars, is the link 26, and this link at itsupper end is secured within the forked end of the arm 27 by means of thepin 28. The

arm 27 ,"is secured to therock shaft 18, by meansof the set screw 29,wlnch is accessible through the opening w thin the.- hearing The box,when the plate 12 is removed.

into

'pipeBO projects from the upper boss 9,

the boiler, while from the lower boss 7, extends the nipple 31 holdingthe tee 32, from.

which extends the connecting pipe 33, the blow-cit cock 34 extendingfrom the lower end ofthc tee as disclosed. The gage is adjusted, in thatafter a suitable amountof water has beenintrodruced into the boiler toraise the float, the indicator 19. will properly indicate the quantityof water within the boiler. As the water rises and falls boiler, thefloat responds to the change in elevation, and this change by means ofthe link 26 and the arm 27 is shown upon the bifacial scale are 20.

The bottom of the float housing may be l 5 kept clear and free ofsediment by means of the blow-oficnck 34. The float is removed andinserted in uncappin the housing.

The parts are all sim e of construction, Bp'sitive of operation an arereadily accessi- 10 6.

Having thus described my said invention what I claim as new and desireto secure by United States Letters Patent is:

' The herein described gage, comprising the 15 combination with atubular housing having a laterall extending bearing box, and an upper anlower threaded boss, of a float reclprocating within said housing, arock shaft within said bearing box projecting beyond said box, an armsecured to said shaft, a link connecting said arm to said float, anindi-- cator carried upon the projecting end of said shaft, and abifacial scale held proximal to said indicator.

In testimony whereof I afiix my signature, in presence of two witnesses.
